【问题描述】：
我在启动 mongo 时遇到了一些问题。我在通过 SSH 连接到的远程机器上使用它。远程机器是我做所有事情的地方（在我自己的机器上什么都不做）。我应该将 bind_ip 从 127.0.0.1 更改为远程机器的 IP 地址吗？但无论我是保留 IP 还是将其更改为远程机器的 IP，我都会收到以下相同的错误消息：
melissa@simba:~$ mongo --version
MongoDB shell version: 2.6.11
melissa@simba:~$ sudo service mongod start
mongod start/running, process 10623
melissa@simba:~$ mongo
MongoDB shell version: 2.6.11
connecting to: test
2015-09-24T19:27:55.279+0000 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused

exception: connect failed
我的远程机器是：Ubuntu 11.10 (GNU/Linux 2.6.35.4-rscloud x86_64)，其中用户 melissa 是 sudoer。
这是我在启动mongod &时收到的消息

There doesn't seem to be a server running with dbpath: /data/db
然后我尝试根据this更改权限，但又出现新错误：

错误在这一行：
exception in initAndListen: 10309 Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating -
我试图终止 mongo，但我仍然得到同样的结果。 melissa@simba:~$ mongod --shutdown 好像没有运行dbpath的服务器：/data/db

我想帮助你，但不幸的是我是一名软件开发人员（就像这个网站上的大多数人一样）。不是Ubuntu 用户（或linux user in general）、server admin 或database administrator。
